情绪调节效应的发展:一个V型发展趋势

从青少年早期到成人早期,个体情绪调节等高级社会认知功能得到进一步完善,对情绪调节的需求也日趋增长。情绪调节的发展是青少年情绪社会化发展一个重要的任务,学会采用有效的调节策略对自身情绪进行调节是青少年社会性发展的一个重要表现。在众多关于青少年社会行为研究中,对负性情绪调节能力的探究最为成熟与深入。以往研究指出,儿童青少年对负性情绪的体验激活和调控失败都是导致其非适应性行为的原因,情绪调节方式的错误选择会与其外化行为问题和和内化行为问题有很大的关联。由于青少年适应性行为的习得是多种社会性发展指标的重叠和交叉作用的体现,我们无法完全理清其中的复杂交互作用,因此从情绪调节策略的使用效应发展入手探讨个体的适应是寻求问题解决的一个可行手段。 以往研究者认为,成熟且有效的情绪调节指的是,个体能够通过控制自身的激活和唤醒以达到情绪性、生理性和社交的适应,最后达成个人的目标。情绪调节的发展也可被看作是从被动式的、有他人参与的调节（例如,社会性参照）逐渐进步为主动的、有意识的根据外部线索进行的情绪调节（例如,根据指导语提示调整自己情绪状态）。 本研究旨在探究不同年龄被试（青少年早期、青少年晚期、成人早期）在按照不同指导语提示要求下增强调节和减弱调节调节效应量的年龄差异。选取上海市初中生被试35名（22男,13女;M = 14.06岁,SD = 0.42 岁, 年龄范围：13-15岁）、高中生被试37名（13男,24女;M=16.56岁, SD=0.56岁, 年龄范围：16-18岁）以及成人被试35名（9男,26女;M = 23.60岁,SD = 1.96岁, 年龄范围：20-29岁）,采用3（年龄：初中生、高中生、成人,被试间变量）? 3（情绪刺激：正性、中性、负性,被试内变量）? 3（调节策略：增强调节、减弱调节、不调节,被试内变量）混合实验设计,使用情绪反应性—调节图片任务（Reactivity and Regulation-Image Task,REAR-I Task）对不同年龄被试情绪调节策略使用的效应量进行考察（Carthy, Horesh, Apter, Edge, & Gross, 2010）。 研究发现,从总体趋势来说,情绪调节策略的效应发展呈V型发展趋势。当不同年龄被试按照指导语要求对其情绪体验进行主动调节时,成人被试的调节效应是最大的,初中生次之,而高中生的调节效应则最低。情绪调节的V型发展趋势与以往研究中关于情绪调节态度以及自我发展的趋势相一致。另外,与增强调节策略的使用相比,减弱调节策略效应的发展是最大的。这可能与中国背景下减弱调节的适应价值有关。     

Effect of Heel Heights on Female Postural Control During Standing on a Dynamic Support Surface With Sinusoidal Oscillations

The authors aimed to investigate female balance or stability control with comparative analysis of the center of pressure trajectory and plantar pressure distribution with different high-heeled shoes while standing on a dynamic surface with multidirectional perturbations. College females with at least 2 years' history of wearing high-heel shoes voluntarily participated in the test with a Novel Pedar insole (Novel, GmBH, Munich, Germany. With heels height increasing, the pressure time integral obviously transfer to the medial forefoot region, with center of pressure trajectory medially deviated significantly, either under anteroposterior or mediolateral perturbations. The passive plantarflexion position of ankle incurred by high heel increased the range of motion in the frontal plane but decreased ankle stability, thus increasing the challenge of body balance maintenance.     

(Re)evaluating the Implications of the Autoregressive Latent Trajectory Model Through Likelihood Ratio Tests of Its Initial Conditions

The autoregressive latent trajectory (ALT) model synthesizes the autoregressive model and the latent growth curve model. The ALT model is flexible enough to produce a variety of discrepant model-implied change trajectories. While some researchers consider this a virtue, others have cautioned that this may confound interpretations of the model's parameters. In this article, we show that some—but not all—of these interpretational difficulties may be clarified mathematically and tested explicitly via likelihood ratio tests (LRTs) imposed on the initial conditions of the model. We show analytically the nested relations among three variants of the ALT model and the constraints needed to establish equivalences. A Monte Carlo simulation study indicated that LRTs, particularly when used in combination with information criterion measures, can allow researchers to test targeted hypotheses about the functional forms of the change process under study. We further demonstrate when and how such tests may justifiably be used to facilitate our understanding of the underlying process of change using a subsample (N = 3,995) of longitudinal family income data from the National Longitudinal Survey of Youth.     

PTSD symptom trajectories: from early to chronic response

This study aimed to identify posttraumatic stress disorder (PTSD) symptom trajectories across the first 12 months following traumatic injury. Three hundred and seven consecutively admitted injury survivors were assessed for severity of PTSD symptoms just prior to discharge, and at 3 and 12 months postinjury. Growth modeling was used to determine the curve that best fit the trajectory for each symptom cluster over the 12-month period. Individuals with 12-month PTSD showed significantly higher re-experiencing, arousal, and avoidance symptoms at eight days posttrauma relative to those without, and these symptoms escalated over time. Those without PTSD maintained their relatively low symptom levels. These findings highlight that individuals who will go onto develop PTSD have a distinctly different symptom course than those who recover.     

Threatened identities: the experiences of women in transition to programmes of professional higher education

The aim of the research described in this article was to investigate how women experience the transition to programmes of professional higher education. The investigation took place in a school of a British university where the professional areas chosen were social work and health care education. Most of the participants were new to the higher education system and were entering as mature students, but a few were making educational transitions and had previous involvement in higher education. As the central focus was an investigation of subjective accounts, a phenomenological perspective was adopted and the methods used were mainly qualitative. A multiple methods approach to data collection was taken. The investigation took place over two phases, covering the period of transition to programmes over two consecutive years. Anxieties were commonly experienced by participants in the transition to their programme. Breakwell's (1986) theory of threatened identities seems useful in understanding the emerging issues. Anxieties could be explained in terms of threats to identity ‘principles’; however, these arose from the social context and coping with them is not always psychologically based. Issues which appear to assist the transition are highlighted. Copyright © 1999 John Wiley & Sons, Ltd.     

Discovery and Revitalization of “Feeling of Hometown” from a Disaster Site Inhabitant's Continuous Engagement in Reconstruction Work: Ethnographic Interviews with a Radiation Decontamination Worker Over 5 Years Following the Fukushima Nuclear Power Plant Accident1

After hometown loss due to the Fukushima Nuclear Power Plant accident, many radiation decontamination workers started to engage in the reconstruction of their hometown. However, little is known regarding the meaning of experience of engaging in such work. We describe the process of such experience through a series of ethnographic interviews over 5 years with a radiation decontamination worker. The process was classified into the following three periods: “recovery of lost land by inhabitants' own hands,” “goal loss and semiotic trap in pursuit of recovery,” and “revitalization of feeling of hometown.” Consequently, the informant overcame the contradiction theorized as a “semiotic trap” that radiation decontamination for physical recovery would make his return to home impossible, and updated his narrative to the revitalization of “feeling of hometown” through continuous engagement in the work by creating a sense for transplacement, in which the individual focuses on the psychological aspects of his/her hometown instead of the physical aspects. Psychological reconstruction for disaster victims requires the discovery and revitalization of feeling of hometown rather than the completion of physical reconstruction.     

Control of Trajectory Modifications in Target-Directed Reaching

Human reaching movements to fixed and displaced visual targets were recorded and compared with simulated movements generated by using a two-joint arm model based on the equilibrium-point (EP) hypothesis (λ model) of motor control (Feldman, 1986). The aim was to investigate the form of central control signals underlying these movements. According to this hypothesis, movements result from changes in control variables that shift the equilibrium position (EP) of the arm. At any time, muscle activations and forces will depend on the difference between the arm's EP and its actual position and on the limb's velocity. In this article, we suggest that the direction of EP shift in reaching is specified at the hand level, whereas the rate of EP shift may be specified at the hand or joint level. A common mechanism underlying reaching to fixed and displaced targets is proposed whereby the EP of the hand shifts in a straight line toward the present target. After the target is displaced, the direction of the hand EP shift is modified toward the second target. The results suggest that the rate of shift of the hand EP may be modified for movements in different parts of the work space. The model, with control signals that vary in a simple fashion over time, is able to generate the kinematic patterns observed empirically.     

Student self‐efficacy narratives: A collaborative co‐constructive method

This article outlines the challenges faced by mature‐aged students transitioning to higher education and presents a method of assisting these students to reflect on ways in which they have overcome past difficulties in terms of their self‐efficacy. For the purpose of the study, self‐efficacy was conceptualised as an individual initiating action to engage in a given task, applying effort to the task, and persisting in the face of obstacles to successfully complete the task. The main aim of the article is to explicate a research method that involves a cyclical and iterative process using qualitative interview data from the population of interest, namely four female mature‐aged students starting an undergraduate degree. The method is highly collaborative, with narratives co‐constructed by the researcher and participants as they are guided in reflecting on those experiences that constitute a sense of self‐efficacy, in narrative and by narrative. The article briefly reports on a research study to illustrate the method and lists the main themes emerging from the narratives. The article concludes with an evaluation by the participants of being involved in the research process, with positive implications for the utility of the method with mature‐aged students and possibly other cohorts.     

Valence and vertical space: Saccade trajectory deviations reveal metaphorical spatial activation

Concepts of positive and negative valence are metaphorically structured in space (e.g., happy is up, sad is down). In fact, coupling a conceptual task (e.g., evaluating words as positive or negative) with a visuospatial task (e.g., identifying stimuli above or below fixation) often gives rise to metaphorical congruency effects. For instance, after reading a positive concept, visual target processing is facilitated above fixation. However, it is possible that tasks requiring upwards and downwards attentional orienting artificially strengthen the link between vertical space and semantic valence. For this reason, in the present study the vertical axis was uncoupled from the response axis. Participants made eye movements along the horizontal axis after reading positive or negative affect words, while their saccade movement trajectories were recorded. Based on previous research on saccade trajectory deviation, we predicted that fast saccade trajectories curve towards the salient segment of space, whereas slow saccade trajectories would curve away from the salient segment. Examining saccadic trajectories revealed a pattern of deviations along the vertical axis consistent with the metaphorical congruency account, although this pattern was mainly driven by positive concepts. These results suggest that semantic processing of valence can automatically recruit spatial features along the vertical axis.
